When you're kissing your girlfriend(or whom ever it is you're kissing) start out slow&soft. Keep your hands on her waist or sides. Once you're to the "totally making out" stage, slowly move you hands down lower to the small of her back.. keep going from there, slowly. VERY slowly. Once you're almost about to have her butt in your hands move your lips down to her neck and lightly make your way up and down it while moving your hands exactly where you want them, pulling her closer. She will LOVE it trust me!
